Genome Editing - GCSE Biology Definition

Genome editing is a powerful scientific technique that allows scientists to make precise changes to the DNA in the cells of living organisms. DNA is like a set of instructions that tells cells how to function. By editing the genome, scientists can fix mistakes in the DNA that might cause diseases, or they can add new traits that could improve health or crop growth. One of the most commonly used tools for this process is called CRISPR, which acts like molecular scissors to cut and edit specific parts of the DNA. Genome editing holds great promise for medicine and agriculture, but it's important to use it responsibly and consider ethical implications.
